the foundation was poured today

I don't know what to make of the standing water. I was up in Montpelier today, chatting with a state employee, and mentioned this project to her. I told her about the ledge, and how we're just going to have a crawlspace instead of a full basement. She said her parents had a crawlspace that when left unattended -- all the windows in the house closed for multiple days on end - got damp and spewed mildew up onto the walls behind all the furniture. Ack!

OK, pictures:
